### Fall 2014 Quiz 3 #8

This is the question...

Consider the following reaction: $NH_{4}HS (s)\rightarrow NH_{3} (g) + H_{2}S (g)$

If the value of Kp os 0.11 $atm^{2}$ at 300 K, calculate the equilibrium partial pressure of $NH_{3}$ (g) starting from pure $NH_{4}HS (s)$.

I don't know how to approach this problem. What information do I use to start solving?

ok so the reactant is a solid so you do not include that in your equilibrium calculation. so your equation is k=P(NH3)*P(H2S). let the products =x. now you have k=x^2, you know k so solve for x and you will have your partial pressures for the products.
